“…The ability of B decachloro o carbo rane to form strong C-H...O and C-H...N hydrogen bonds (ΔH = 6-8 kcal mol -1 ) with DMSO and DMF was demonstrated by IR spectroscopy. 64, 65 More recently, it has been shown that unsubstituted carboranes are also able to form hydrogen bonds with ΔH = 3 kcal mol -1 . 66- 67 The major achievements in this field were reviewed in publications.…”

Important features of the chemical behavior of icosahedral carboranes are considered. The ways of introducing functional groups at the carbon and boron atoms of carboranes by conventional methods of organic chemistry and methods applicable only to carboranes are discussed. The latter methods include transformations of dicarbadodecaborate (14) dianions. Examples of the enantiomer ic resolution of optically active carboranes, whose chirality is associated with the molecular asym metry, are given. The diversity of chemical transformations of carboranes is exemplified by in tramolecular nucleophilic rearrangements, cross coupling reactions, and the formation of chelate metallacycles.
